Can anyone help me with this question? I just purchased a Stoeger Cougar 8040. Took it to the range yesterday and the pistol handles and shot great. Very accurate right out of the box! The issue I have is after I started cleaning it I noticed that it has a plastic guide rod! I would like to know if anyone has had a problem with this, and if it is possible to replace it with a Beretta PX4 Storm guide rod? They seem identical mechanically! All advice would be appreciated.
